In addition to what others have explained, local imports are necessary
for template mixins:

I have dabbled in D a few times over the past few years, but
still pretty inexperienced. I decided to work on some project
euler problems in D for fun. A problem requires detecting a
palindrome.
The terrible way is something like:
void reset(Object o)
in {
assert(!(o is null));
}
body {
auto p = cast(ubyte*)*cast(void**)&o;
auto ci = o.classinfo;

You could always copy the init back over it. For a struct:

for a class... well, the code is a lot u
